 In my past I did a lot of geometric programming. Something we had to be be very careful of was degenerate intersections and numerical tolerance. That is the first thing I thought of when you mentioned an odd number of intersections. If you are at or very close to the endpoint of a line segment, it might miss, or hit, when it really shouldn't. Sometimes you have to catch them and handle them specially (*cough* hack *cough*). Like artificially extend the vector slightly to see if it intersects within the segment, or keep intersections that are questionable conditional until you can tell the count is right. For instance, imagine two line segments whose common endpoint is on or very close to the segment you are intersecting with. Really, there should be only one intersection there. But if you count each segment endpoint as colliding, then you get two intersections where you should have only one. Or vice versa, you might discard both because you think they are off the line, and have zero where you should have one. Sorry, this is off the top of my head remembering stuff we had to deal with a long time ago.
